Unknown Stripped lines in the filer pannel (on Arkenfox)

[I-I-IT]

Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• This is not a support issue or a question. For support, questions, or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

So, I've noticed that on my config on pages with a lot of tracker, the uBo pannel displays stripped lines, that can't be interacted with. Screenshots below.

The issue isn't present with Brave Beta, or a new Firefox profile, with or without Arkenfox(tested with the same settings). I have tested disabling other extensions, but this doesn't fix the problem. I also have tried going minimal with the filter lists, but doesn't work either. As you can see, I am on Hard Mode.
